Deploying and Configuring the Cisco 9800 Virtual Wireless Controller for the First Time

Deploying the new Cisco 9800-CL wireless controller is fast and easy, and by using the built-in workflows, a new wireless network can be deployed in only a few minutes. In this post, I’ll review how to deploy the virtual wireless LAN controller in VMware ESXi and stand up a very simple WLAN. We’ll also take a look at some potential gotchas and some noteworthy differences between how the new WLC is configured compared to the AireOS WLC.
